Use your own ElevenLabs voices for AI voiceovers

Some AI models allow you to use your own or cloned voices. One of the most popular models that supports this is the ElevenLabs model.

Steps to use your own voices

To use your own voice in your videos you will need an ElevenLabs account and an active subscription. With that, follow these steps:

Create an API Key

• Go to https://elevenlabs.io/app/settings/api-keys
• Click on Create API Key
• Enter a name for your API Key (like JSON2Video API Key)
• Click on Create
• Copy the API Key to your clipboard and save it in a secure place for later use

Connect your ElevenLabs API Key as JSON2Video connection

• Go to https://json2video.com/dashboard/connections
• Click on Add a new connection
• Choose an ID (a name for your connection), for example my-elevenlabs-api-key
• Choose apikey as the connection type
• Click on Continue
• Enter your API Key
• Click on Save

Create or clone a new voice

• Go to https://elevenlabs.io/app/voice-lab
• Click on Add a new voice
• Choose between Voice Design, Instant Voice Clone, Professional Voice Clone and Voice Library
• In case you are cloning a voice, you will need to upload a recording of at least 2 minutes of the voice you want to clone

Get your voice ID

• Go to https://elevenlabs.io/app/voice-lab again
• Look for the voice you just created or cloned
• Click on the "View" button on the right side of the voice
• A right side panel will open with the voice details
• Copy the Voice ID (button at the bottom right of the panel) to your clipboard and save it in a secure place for later use. It will look like 42xgKaeATtWRPTmYPyGQ.

Use your voice in your videos

You can now use your voice in your videos by specifing your voice ID in the voice property.

Example:

{
    "resolution": "full-hd",
    "scenes": [
        {
            "elements": [
                {
                    "type": "voice",
                    "model": "elevenlabs",
                    "connection": "my-elevenlabs-api-key",
                    "text": "That's one small step for a man, one giant leap for mankind.",
                    "voice": "42xgKaeATtWRPTmYPyGQ"
                }
            ]
        }
    ]
}

require 'vendor/autoload.php';

use JSON2Video\Movie;
use JSON2Video\Scene;

// Create and initialize the movie object
$movie = new Movie;
$movie->setAPIKey(YOUR_API_KEY);
$movie->resolution = 'full-hd';

// Create the scenes of the movie

// Create SCENE 1
$scene1 = new Scene;
$scene1->addElement([
	'type' => 'voice',
	'model' => 'elevenlabs',
	'connection' => 'my-elevenlabs-api-key',
	'text' => 'That\'s one small step for a man, one giant leap for mankind.',
	'voice' => '42xgKaeATtWRPTmYPyGQ'
]);
$movie->addScene($scene1);

// Finally, render the movie
$movie->render();

// Wait for the movie to be rendered
$movie->waitToFinish();

let movie = new Movie;
movie.setAPIKey(YOUR_API_KEY);
movie.set("resolution", "full-hd");

// Create the scenes of the movie

// Create SCENE 1
let scene1 = new Scene;
scene1.addElement({
	"type": "voice",
	"model": "elevenlabs",
	"connection": "my-elevenlabs-api-key",
	"text": "That's one small step for a man, one giant leap for mankind.",
	"voice": "42xgKaeATtWRPTmYPyGQ"
});
movie.addScene(scene1);

// Finally, render the movie
movie.render();

// Wait for the movie to be rendered
movie.waitToFinish();
